2 Computer Errors Delay Flights in East

A pair of computer problems in a two-hour span at a regional air traffic control center in Jacksonville, Fla., grounded jets along the East Coast, delaying some flights by nearly an hour. The center was without radar about an hour because technicians failed to restart the flight data computers after routine maintenance, said Bob Ropelewski, a Federal Aviation Administration spokesman. The radar loss caused delays in Tampa and Orlando. An hour later, keyboards on air traffic computers temporarily stopped working, forcing the center to turn away Florida-bound flights, Ropelewski said. Delays and groundings were reported in New York, Charlotte, N.C., and Atlanta.
